Al-A'raaf • EN-TAFSIR-IBN-ABBAS
﴿ وَمَنْ خَفَّتْ مَوَٰزِينُهُۥ فَأُو۟لَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُم بِمَا كَانُوا۟ بِـَٔايَٰتِنَا يَظْلِمُونَ ﴾
“whereas those whose weight is light in the balance - it is they who will have squandered their own selves by their wilful rejection of Our messages.”
(And as for those whose scale is light) with good deeds: (those are they who lose their souls) by being punished (because they disbelieved Our revelations) Muhammad (pbuh) and the Qur'an.
